While staying in a glass igloo doesn't sound super warm, you'll be plenty toasty at the Igloo Village of Hotel Kakslauttanen in Finland. Their small design allows them be heated efficiently, and the glass ceiling gives a great opportunity to view the Aurora Borealis.

The Whitepod Eco Resort located in the village of Les Cerniers in the Swiss Alps offers a private ski resort, mountain chalets and 15 geodesic-dome pods that offer low-impact accommodations. Guests tour the resort via skis, snowshoes, snowboards and by dog sled. Cozy up inside one of these gorgeous rooms and fall asleep as the snow blankets your pod.

Made from snow and ice, the temporary Hotel de Glace is open to the public during the coldest months. Rent one of their artistically designed rooms, enjoy cocktails at the ice bar or even get married in their beautiful ice chapel. Just be sure to get there before spring, when it all melts away.

Part of the Swiss Alpine Club’s hut system, the Monte Rosa Hut looks more like an evil villian’s lair than a cozy winter hostel. Powered by solar panels, and making use of energy efficient design, the student-designed hut is almost totally self-sufficient. To get there, you’ll need to ski in and ski out.

Sweden’s Icehotel is yet another mind-boggling artistic endeavor that only takes place during the coldest months of the year. With a new design each year, it’s like going to a new place every winter. Last year’s design was inspired by Tron and featured energy efficient lighting wire embedded in the ice. We can’t wait to see what they come up with this year.
